When do subterranean termites make their exit tubes? I live in northeast Texas.
There is no hard fast time but in general, most swarmers and their exit tubes will appear in the spring. Where you live, this will be from February to May. That being said, they can and usually do emerge at odd times throughout any calendar year. I’ve seen them swarm in the summer, fall and winter too as well so nothing is etched in stone when it comes to termites.
The most important thing to realize with termites is that if you’re finding their tubes, flying swarmers or live workers, it’s time to treat the structure or get it retreated. More info can be found in our article here:
